SECOND SUPPLEMENT 



TO THE 



PRELIMINARY LIST OF THE COLEOPTERA 

 OF THE OXFORD DISTRICT, 



Published in tlie Report of the Ashmolean Natural 

 History Society of Oxfordshire for 1906. 



By JAMES J. WALKER, Hon. M.A., R.N., F.L.S. 



Two years have elapsed since the publication in the 

 Report of the Ashmolean Natural History Society for 1907 of 

 the First Supplement to the Preliminary List of Coleoptera of 

 the Oxford IDistrict. During that interval, the investigation 

 of our exceedingly rich and interesting beetle-fauna has been 

 pursued steadily, with the result that the number of additions to 

 the list of species already known is I trust sufficient to justify 

 the compilation of the present ''Second Supplement." These 

 additional species include a large proportion of forms of rare 

 and local occurrence, especially in the family StaphyUnidce. 

 This extensive and difificult section of the Coleoptera has been, 

 as previously, closely studied and worked by my friend Mr. 

 Joseph Collins of the " Hope Department," and his efforts 

 have resulted in a large number of very interesting additions 

 to the local list, in many cases examined and confirmed on 

 the authority of Mr. G. C. Champion. Some very good con- 

 tributions have also been made by Messrs. W. Holland and 

 A. H. Hamm, and by Prof. T. Hudson Beare, Mr. H. St. J. 

 Donisthorpe, Mr. P. Harwood, and Mr. J. R, le B. Tomlin, in 

 occasional visits to the district. Of course it is hardly to be 

 expected that additions to the list of species occurring in the 

 district (which may now be considered as on the whole pretty 

 well worked) will come in as rapidly in the future as in the 

 past. It is only fair to say, however, that one or two localities 

 of old repute near Oxford, which are now closed to Naturalists 

 in general, might well be expected to yield many rare and 

 interesting additional species of Coleoptera as well as of other
